What Sandberg Goldberg Bernthal Family Foundation does
Programs
The foundation works to build a more equal and resilient world and its activities are primarily funded by contributions provided by the founders via their donor advised fund and royalty income derived from copyrights. The copyrights entitle the foundation to royalty revenues related to sales of two books authored by one of the founders. The foundation brings people together to support each other through two key initiatives: leanin.org and optionb.org. Leanin.org empowers women to achieve their ambitions. It runs programs that counter gender stereotypes and advance opportunities for all women. Leanin.org supports women in three ways: 1)building community by collecting and exchanging ideas, information, and stories; 2)offering educational materials, lectures, and partnering with experts in the field of gender studies; 3)facilitating the development of lean in circles, small groups that meet monthly to encourage and support each other in an atmosphere of confidentiality and trust.
$10,146,808 spentOptionb.org helps people build resilience and find meaning in the face of adversity. It runs programs that provide resources to people facing adversity such as grief and loss, health, illness and injury, abuse and sexual assault, and divorce and family challenges. Optionb.org supports men and women in three ways: 1) building community by collecting and exchanging ideas, information, and stories; 2) offering educational materials, lectures, and partnering with experts in the field of adversity studies; 3) facilitating the development of option b support groups: online groups that provide encouragement and support in an atmosphere of confidentiality and trust.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2019 to 2020, from $4.9M to $12M (+138%).
Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

From the IRS filings of SANDBERG GOLDBERG BERNTHAL FAMILY FOUNDATION’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
SANDBERG GOLDBERG BERNTHAL FAMILY FOUNDATION leans on a few funders — its largest provides 100% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
100% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund SANDBERG GOLDBERG BERNTHAL FAMILY FOUNDATION.
Largest funder’s share by year: 2017 98% · 2018 100% · 2019 100% · 2020 100% · 2021 100% · 2022 100% · 2023 100% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
100% of SANDBERG GOLDBERG BERNTHAL FAMILY FOUNDATION's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $1k that is directly attributable, 100% of it comes from funders outside California, across 1 state.
Funder states come from each funder’s own filing. $103M arriving through sponsors registered in 3 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
